Injury to these soft tissues during delivery can substantially affect a woman's postpartum quality of life. In recent years, research has increasingly focused on evaluating pelvic floor structures prior to labor to determine whether functional or anatomical changes contribute to the labor process and its outcomes. Transperineal ultrasound has emerged as a promising tool for objectively assessing the preparedness of pelvic floor musculature for vaginal delivery. This paper summarizes current scientific evidence on the use of transperineal ultrasound in the assessment of selected dimensions of pelvic floor structures and their impact on labor progression. Several studies have demonstrated that significantly reduced dimensions of the genital hiatus are significantly associated with an increased risk of operative delivery and a prolonged second stage of labor. In the future, transperineal ultrasound may help identify women with an elevated risk of delivery-related complications. Such identification could support individualized strategies to mitigate these risks or guide the selection of the most appropriate mode of delivery, considering other clinical and obstetric factors. However, at present, pelvic floor assessment via transperineal ultrasound cannot be considered as a standalone marker for determining optimal delivery strategy. Childbirth remains a multifactorial process, and pelvic floor morphology represents only one of many variables influencing its course. Further research is needed to validate the clinical utility of this method and to establish its role in obstetric decision-making.</p>","PeriodicalId":43333,"journal":{"name":"Ceska Gynekologie-Czech Gynaecology","volume":"91 2","pages":"148-156"},"PeriodicalIF":0.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147876117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservative treatment mainly includes pelvic floor muscle training, where the effectiveness is limited by the patient's ability to actively engage the muscles and long-term compliance. An alternative is electrical stimulation of the pelvic floor, which, however, is sometimes painful and requires invasive application of probes to the pelvic floor. A new option is high-frequency electromagnetic stimulation using High-Intensity Tesla Stimulation (HITS) technology, which induces intense muscle contractions without the need for insertion of probes or electrodes and with higher patient tolerance. The aim of the study was to evaluate the effectiveness of six HITS sessions in women with SUI - based on subjective assessment by patients and objective assessment of muscle strength according to the modified Oxford scale (MOS) and electromyographic activity of the pelvic floor using the Multiple Array Probe Leiden (MAPLe) probe).</p><p><strong>Methods: </strong>A prospective study was conducted at the urogynecological center Gyn-Line in Brno from February to September 2025.

One of the principal biological contributors is the high incidence of aneuploidy in oocytes and embryos, a risk that increases markedly with advancing maternal age. Successful implantation requires not only a genetically normal embryo, but also a receptive endometrium and a functional feto-maternal dialogue. Nevertheless, even after the transfer of a euploid embryo, implantation occurs in only 60-70% of cases, underscoring the importance of the uterine environment for successful embryo attachment. A key element in the implantation process is the immunological balance at the feto-maternal interface. Uterine natural killer (uNK) cells constitute the dominant lymphocyte population within the decidua and play essential roles in implantation, placentation, and fetal immunotolerance. Their function is mediated, among other mechanisms, by interactions with trophoblast cells through killer-cell immunoglobulin-like (KIR) receptors and human leukocyte antigen C (HLA-C) antigens. Imbalances in these interactions can contribute to pregnancy pathologies such as implantation failure, miscarriage, preeclampsia, and fetal growth restriction. Although current diagnostic methods enable assessment of immunological conditions in reproductive tissues, interpreting these findings in the context of fertility or infertility remains challenging. Emerging research directions include the application of molecular genetics and detailed characterization of distinct NK cell subpopulations.
